Head of College’s Office

The Head of College is the head and ranking officer of Berkeley College, responsible for the college’s intellectual, social, athletic, and artistic life. The college is administered through the Head of College’s Office, which is staffed by an operations manager, senior administrative assistant, and student aides. The Head of College works closely with the Dean, Resident Fellows, the Dining Hall Manager, and other staff to build the best possible community for our students.

Head of College David A.D. Evans    

David A.D. Evans is a member of the faculty of the Department of Earth & Planetary Sciences. Professor Evans focuses his research on plate tectonics, the past motions of continents across Earth’s surface. He is director of the Yale Paleomagnetism Laboratory, which traces this movement by measuring fossil magnetism preserved in ancient rocks from around the world.

His work has elucidated the configurations of vanished supercontinents named Pangea, Rodinia, and Nuna (each separated by about 600 million years); characterized the geometry of Earth’s ancient magnetic field; and provided evidence for globally engulfing “Snowball Earth” ice ages that occurred deep in Earth’s history, around the time when animals were first evolving. He earned his Ph.D. at the California Institute of Technology and conducted postdoctoral research at the University of Western Australia before joining the Yale faculty in 2002. He especially enjoys sharing his knowledge of the world’s geology, climate, and natural resources with undergraduate students in his introductory-level courses at Yale.

Professor Evans grew up in the suburbs of Milwaukee, Wisconsin, and graduated from Yale College (where he was a resident of Berkeley) in 1992. His is a family of Berkeleyites: his father is BK’62 and his sister is BK’89. Aside from cheering on, often fruitlessly, his favorite professional sports teams (the Green Bay Packers and Milwaukee Bucks), Head Evans’s main extracurricular passion is music, regularly playing contrabass in the Berkeley College Orchestra and occasionally slapping a bass guitar or reciting old-school hip-hop lyrics.

The Associate Head of Berkeley College, Lely Dai Evans, is a language educator and educational consultant. Raised in Taiwan, Lely received her undergraduate degree at Occidental College and a master’s degree in early violin music performance practice from The University of Western Australia. She also loves cooking and brings many aspects of food preparation, as well as music, into her teaching repertoire.

The Evanses are joined by their cavachon dog named Brie, who is hypoallergenic and growls only when she has not received the proper amount of petting or other attention from members of her international fan base.

Sarah Layedra, Operations Manager

Sarah Layedra joined Berkeley College in June 2017 and is the Operations Manager for Berkeley College.  With direction from Head of College David Evans, Sarah is responsible for managing the financial and administrative operations of Berkeley. This includes overseeing the college’s finances, events, and facilities. She is also the coordinator of the Paul Mellon Fellowship. In addition, Sarah oversees special projects, and serves as liaison between the college and the Yale College Business Office. This deceptive description fails to explain how truly vital Sarah is in maintaining the collegiate environment.  She manages every facet of college life including the oversight of College funds, fellowships and events. Because of Sarah’s involvement in many aspects of Berkeley College life, she will often be a student’s first recourse for questions about fellowships and college life. At most every event, you will find her working behind the scenes with Naomi DiGioia and the College Aides to ensure its success.

Sarah’s favorite free time activity is spending time with her husband Jose and son Andrés.

Sarah is in F15 and can be reached by e-mail at sarah.layedra@yale.edu or at (203) 436-2899 on weekdays. 


Naomi DiGioia, Senior Administrative Assistant II

Naomi DiGioia is the Senior Administrative Assistant for Berkeley College and handles the day-to-day business of the Berkeley College Administrative Office.  Naomi works with Sarah and the College Aides to manage college activities as well as the bustling Head of College’s Office. Naomi is the point person for any questions about college life and facilities (including scheduling use of public spaces like the Multipurpose Room, BK Gym, the Music Room, and the Mendenhall Room). If Naomi or the College Aides don’t have the answer, they will be able to direct you to someone who can help. Naomi is very efficient in helping you with any need you may run into including taking care of your chocolate cravings. She is also the person to see if you find yourself wrapped in a towel and locked out of your room. If you need to make an appointment with the Head of College, contact Naomi who is always willing to lend a hand or an ear to students who need it.  

Naomi has worked at Yale since 2004, working for Yale College Summer Session before joining Berkeley College in June of 2017.  Born and raised in the New Haven area, Naomi now lives in beautiful Beacon Falls with her husband and daughter.  In her spare time, Naomi likes to practice yoga, read, cook, and spend as much time as she can with family and friends.

Naomi is in F15 and can be reached by e-mail at naomi.digioia@yale.edu or at (203) 432-0501 on weekdays.


College Aides

College Aides are sophomores, juniors, and seniors who have been chosen by the Head of College to assist Sarah and Naomi in the running of the college. They help organize the many events sponsored by the Head of College’s office, from the Freshman Picnic at the beginning of the year to the Berkeley Commencement in May. Each is responsible for specific areas of the College, including the Berkeley Buttery, and the Library. They can often be found in the Head of College’s Office helping make life slightly less stressful for Berkeleyites.

The 2020-2021 Berkeley College Aides Application will be avaliable in January 2022.

“Neal is a junior here in Berkeley College majoring in both Philosophy and Ethics, Politics, and Economics with a focus in legal theory (but who really knows). Born and raised in New Haven, Neal loves showing off his favorite city in the world to out-of-town Yalies! Neal is also a tour guide at the Yale Center for British Art (check out his tour titled “Fear and Power”), host of a radio show (recently been digging Goose’s 20:21 minute cover of Vampire Weekend’s “2021”), and Opinion editor at the Yale Herald (he loves creative writing in his free time). Around Berkeley, you’ll probably find him in the gym or the dining hall, sometimes bouncing between the two for prolonged periods of procrastination. Neal is so excited to spend the next two years in the best residential college on campus!”
